Starting with the Polaris 10, we have 2304 stream processors all clocked at 1266MHz, with the Polaris 10 powering both the RX 480 and RX 470 cards. The RX 480 is going to be a beast of a card, offering R9 Nano/GTX 980 levels of performance with 4GB/8GB variants ($199/$229 for the reference models). It'll be great for 1080p and 1440p gaming, as well as VR gaming - with FreeSync support, and DisplayPort 1.3/1.4 (and HDR, too).

The Polaris 11 GPU will power the lower-end, eSports-aimed RX 460 card, which will feature 1024 stream processors, with no GPU clock speed numbers confirmed just yet. We know that there will be 2GB and 4GB models of the RX 460 offered, with a 128-bit memory bus and memory bandwidth of somewhere around 112GB/sec. The RX 460 features a pretty damn good 2.8x performance per watt improvement over the previous GCN cards like the Radeon R7 360. The Radeon RX 460 will also have a TDP of only 75W, so you don't need to use a PCIe power connector - which is going to be awesome for gamers who don't have a huge budget in terms of money, and power consumption/bills.
